This invention relates to stationery andA more particularly to combinedwriting sheets and envelopes.

An important object of the invention 1s to provide a number of novelforms of Writing paper adapted to be folded to form resultant envelopessuitable formailing.

A further object is to provide a sheet of writing paper which is adaptedto be folded to form a resultant envelope either with or without atransparent window therein, certain portions of the edges of the sheetof paper being gummed whereby the portions of the envelope may besecured together for mailing.

A further object is to provide a sheet of writing' paper which may be ofany desired size within reasonable limits, the sheet being adapted to befolded to form a resultant envelope, portions of the sheet beingarranged wholly within theenvelope.

Other objects and advantages of the invention will become apparentduring the course of the following description.

In the drawings, I have shown several embodiments of the invention. Inthis showing:

Referring to Figures 1 to 3 inclusive, the numeral 10 designates as awhole a blank forming a sheet of writing paper. The blank is providedwith relatively large end sections 11 and 12 respectively connected byintegral intermediate portions 13 and. 14, as shown. The sections 11 and12 of the envelope are perforated along lines slightly spaced from andparallel to the free edges thereof, as indicated at 15. The portionsofthe section 12 which lie between the perforated lines 15 and the freeedges of the section are gummed as at 16 to provide means for sealingthe envelope, as will be described. The sectiony 13 is equal in width tothe sections 11 and 12 as shown and this section also is perforatedalong lines parallel to and slightly spaced from the free edges, as at17. The spaces between the perforations 17 and the edges of the portion13 also are gummed as at 18. The portion 14 of the sheet is relativelynarrow, the edges thereof being substantially in alinement with theperforations 15 and 17 at the sides of the sheet. The section 11 of thesheet in the form of the invention being described is preferablyprovided Wit-h a transparent Window 19 which may be formed in anydesired manner. Thesheet to be folded along lines 20, 21 and 22 whichmay be indicated by printing dotted lines across the sheet, by scoringthe sheet or indicating these lines in any other desired manner. Thewidth of each section 13 and 14 is preferably equal to slightly lessthan'the distance between the line 20 and the window 1 9 for a. purposeto be described.

.When using the form of the invention just described in correspondence,the name and address of the person to Whom the letter is being sent iswritten transversely across the section 12 at a point corresponding inposition to the window 19 when the envelope .is folded as suggested inFigure2. The letter then may be written lon the sheet as far as desired,whereupon the sheet is folded along the lines 20, 21 and 22 whereby thesections 18 and 14 will lie between the `sections 11 and 12. It will beapparent that by-moistening the gummed portions 18, the latter may besecured against the inner face of a portion of the adjacent margin ofthe sheet 11. Similarly, it will be obvious that the gummed margin 16may be moistened and is adapted plan view showing a blank t when theopposite sides of the envelope are pressed together the gummed margin 16will adhere to the back of the gummed margin 18fthe'intermediateportions of the sheet may be folded into the resultantenvelope without interfering with the vision of the name and addressthrough the transparent window. By reducing the width ofthe section 14,the gummed margins 16 and'18 will be secured together and these marginsin turn will besecured to the margins of the section 11. Thus it will beobvious that Athe intermediate section cannot be withdrawn from theenvelope without mutilating it. In Fig' jure ,3 of the drawings, therelative positions of the various sections of the sheet are lndicatedwhen the envelope is folded, When 1t is desired to open the envelope,the addressee mere-ly tears the sheet along the perforated lines anddiscards the margins thus severed,

' whereupon the sheet may be opened and read as the usual letter sheet.

In Figure 4 of the drawings, I have shown a modified form of .theinvention similar to the form previously described except that thewindow is eliminated. In this form of the invention, it will be obviousthat the sections 13 and 14 may, be made somewhat wider so that thecentral fold 21 may extend substantially to the perforated lines 15 atthe ends of the sheet as indicated in detail in Figure 5.

In Figure 6 there is shown a further modication wherein the portions ofthe sheet which are folded into the interior of the envelope areprovided at one end of the sheet instead of intermediate the endsthereof. In this form of the invention, two adjacent sections 23 and 24are provided adjacent one end ofthe sheet and these sections -rnay bedivided by a dotted or scored line 25, as indicated. The section 23 lmaybe provided with the usual transparent window 26. The opposite edges ofthe sections 23 and 24 are perforated as at 26 and the portions of thesection 23 between the perforations 26 and the edge of the sheet may begummed as at 27. The free edge of the section 23 is provided with a flap28 having gummed edges 29. The opposite end of the sheet is providedWith integral extended sections 30 and 31. The width of the sections 30and 31 corresponds to the distance between the perforated lines 26, asshown. The sections 24, 30 and 31 may be divided by the dotted or scoredlines 32.

In Figure 7 of the drawings, I have indicated the vmanner in which theform of the sheet just described may be folded. It will be obvious thatthe sheet is folded transverselY along the center line 32 and subsequentmay be folded along the line25 and outer 'ne 32. Thus the sections 23and 24 will be brought opposite each other with the sections 30 and 31arranged therebetween. The gummed sections 27 then may1 be moistened tosecure them to the margins of the section 24, as will be obvious and thegummed margin 29 may be moistened and bent back against the outer faceof the section 24 to which it is to be secured. In Figure 8 of thedrawings, I have shown a sectional view indicating the relativepositions \of the sections of the sheet when the resultant envelope isfolded. It will be obvious thatthe name and address is written onsection 31 so that they will be visible through the transparent window.

The form of the sheet illustrated in Figures 9 and 10 is similar to theform just described except that the window is eliminated. In the formsofthe invention s hown in Figures 6 to 10, the sections 30 and 31 may beequal in width to the sections 23 and 24. In Figure 10 of the drawingsthere is shown a detail sectional view taken at right angles to theplane of Figure 8 showing the margins of the sections 23 and 24 securedtogether with the sections 30 and 31 lying therebetween. In mailing theform of the sheet shown in Figure 9, it will be obvious that theenvelope will be addressed in the usual manner. A further modificationof the invention is shown in Figure 11 of the drawings. In this form ofthe inventionthere is illustrated a sheet indicated as a whole by thenumeral 33 which comprises a pair of sections 34 and 35 adjacent oneend. 'Ihe section 34 may be provided with the usual transparent window36. The ends of the sections 34 and 35 are provided with alinedperforations 37 and the section 35 adjacent its edge is gummed as at 38.The outer sides of the sections 34 and 35 are similarly perforated as at39 and the portions of the sections between these perforations and theedges of the sections are gummed as at 40. The sheet 33 is furtherprovided with integral sections 41 and 42 divided from the sections 34and 35 by a dotted or scored line 43 which divides the sheetsubstantially transversely. The sections 35 and 42 are similarly dividedfrom the sections 34 and 41 by a longitudinally dotted or scored line44. The upper edge of the section 42 is perforated as at 45substantially-in alinement with the perforations 39. The-lower edge 46of the section 41 is substantially in alinement with the perforations 39of the section 34. The length of the sections 41 and 42 is substantiallyequal to the length of the sections 34 and 35 from theperforations 37 tothe line 43. I

When utilizing the form of the invention iso just described, the nameand address is writ-- ten on the section 41 opposite the transparentmember 36. The sheet is then folded first along the line 43 and-thenalong the line 44, as indicated in Figure 12 of the drawings. Thevarious gummed portions of the sheet are then moistened and the margin38 of the section 35 will adhere to the corresponding margin of thesection 34 while the upper gummed portion of the section 35 will adhereto the portion of the section 42 above the perforated line 45. The lowergummed portion 40 of the section 34 will adhere tothe back of the uppermargin of the sheet 42, as will be obvious.

The form of the invention shown in Figure 15 is substantially the sameas the form just described except that the transparent window isomitted. The envelope formed by this form of the device will beaddressed in the usual manner as will be understood. In Figure 14 of thedrawings, I have shown a section taken substantially at right angles tothe plane of the section of Figure 13 showing the margins outwardly ofthe perforated lines 37 secured together.

The methods of using the envelopes will be obvious from the foregoingdescription. It will be obvious that each of the sheets provides aportion folded within the resultant envelope and adapted to be retainedtherein against unauthorized examination until received by theaddressee. Each of the envelopes thus formed may be opened merely bytearing them along the perforated lines and dischargingthe margins thussevered. vIn all the forms ofthe invention de-l scribed, the sheetsformed by tearing along the perforated lines will be rectangular inshape corresponding generally to the usuall letter sheet. The linejoining the flap 28 to the sectioni23 in Figures 6 to 10 inclusiveA maybe perforated to permit the Hap more easily to be torn from the sheet.

It is to be understood that the forms of my invention herewith shown anddescribed are to be taken as preferred examples of the integral sectionadapted to be arranged wholly between said envelope sides, said lastnamed section being materially smaller than said envelope sides wherebya portion of one of said sides is visible through the transparent windowin the other of said sides.

2. A letter sheet including a pair of sections of substantial equalsize'adapted to form opposite sides of a resultant envelope when thesheet is folded, one of said sections being arranged at the end ofthesheet and being provided -adj acent the extremity of the sheet with atransparent window, said sheet being further provided with a pluralityof integral sections adapted to be arranged Wholly between said envelopesides, said plurality of sections being materially smaller than saidenvelope sideswhereby they terminate a substantial distance from theextremity of the sheet adjacent said window whereby one of said envelopesides is visible through said transparent window.

3. Ay letter sheet marked by a series of spaced parallel transverselines to indicate a plurality of sections, two of 'said sections beingequal in size and adapted. to form opposite sides of an envelope whenthe sheet is folded, one of said sections being provided with atransparent window, the other of said sections being arranged whollybetween said envelope sides and terminating inwardly of said transparentWindow whereby the other of said envelope sides is visible therethrough.

f 4. A letter sheet marked by a series of spaced parallel transverselines to indicate a pair of relatively large rectangular end sectionsand a plurality of relatively narrow intermediate sections, the two endsections being adapted to form opposite sides of `a resultant envelopewhen the sheet is folded, one of said end sections, being providedadjacent the extremity of the sheet with a transparent. window, saidintermediate sections terminating a material distance from the edge ofthe resultant envelope adjacent said window whereby the other of saidend sections is visible therethrough.

5. An envelope `constructed in accordancel with'claim .4 wherein saidend sections are provided with extended marginal portions,

" the marginal portions of one of said end sections being gummed andadapted to engage against the marginal portions of the other of said endsections.

6. An envelope constructed in accordance with claim 4 wherein said endsections are provided with extended marginal portions, the marginalportions of one of said end sections being gummed and adapted to engageagainst the marginal portions of the other of said end sections, one ofsaid intermediate portions being provided with an edge marginal portiongummed on one side thereof and adapted to be arranged between the otherof said marginal portions.
